Abstract

It is generally known that the velocity of the airflow through the radiator is a function of the vehicle speed and the °»heat transferred by a radiator is a function of the airflow rate across the radiator°… This paper presents a ComputationalFluidDynamics (CFD) modeling simulation of mass flow rate of air passing across the tubes of an automotive radiator. An introduction to mass flow rate and its significance was elaborated in order to understand the complications involved in the research and thereafter arrive at the objectives. Knowing the geometry of tube in radiator is the crucial application of CFD to numerically model and thereby analyze the simulation. The Air flow simulation is conducted using commercial software ANSYS 12.1 The CFD process starts with defining the geometry using the CAD software °∆Solid works°« and then it is followed by the meshing which create the surface mesh as well as volume mesh accordingly. After meshing, the boundary conditions are defining before solving that represents flow fields of the simulation. The flow characteristics are then analysed, compared and verified according to known physical situation and existing experimental data. The results obtained serve as good database for the future investigations.
